| titleOfInvention | Method for denitration of waste incineration flue gas by ammonia in waste leachate |
| abstract | A method for denitration of waste incineration flue gas by ammonia in landfill leachate belongs to the technical field of high-concentration ammonia nitrogen treatment of landfill leachate. The pretreated percolate firstly enters an adjusting tank to adjust the pH value of the wastewater to be more than 10, then the temperature of the wastewater is raised to about 80 ℃ through a heat exchanger, the wastewater is sent into a stripping tower, water flows downwards from the top of the tower, and the water flows in countercurrent contact with high-temperature steam introduced from the bottom of the tower through a filler or a distributor; discharging ammonia-containing steam from the top of the stripping tower, and generating ammonia water after passing through a partial condenser at the top of the stripping tower; finally preparing ammonia water with the concentration of 8-16% by controlling the reflux amount of the ammonia water and the operating temperature of a partial condenser at the top of the tower, and storing the ammonia water in an ammonia water storage tank; gas-phase ammonia gas generated by the dephlegmator can be directly blown to a hearth through the induced draft fan to carry out denitration reaction; and the effluent of the stripping tower enters a percolate post-treatment system after waste heat recovery and neutralization to continue to be treated until the effluent reaches the standard and is discharged. |
